Embraer delivered the second KC-390 multi-mission aircraft to the Portuguese Air Force (FAP). The platform includes standard NATO (North Atlantic Treaty Organisation) equipment already integrated into the aircraft and meets the requirements set by the National Aeronautical Authority (AAN) of Portugal. In 2019, FAP ordered five KC-390, including a comprehensive services and support package and a flight simulator. The first aircraft entered into service in October 2023 at Beja Air Base.

The C-390 can carry more payload (26 tonnes) compared to other mediumsized military transport aircraft and flies faster (470 knots) and farther, being capable of performing a wide range of missions operating on temporary or unpaved runways. The aircraft configured with air-to-air refuelling equipment, with the designation KC-390, has already proven its aerial refuelling capacity both as a tanker and as a receiver.
